Scaffolding Certification

The Scaffolding Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests scaffolding competence — scaffold types, components and erection, platforms, guardrails and access, inspection, tagging and the competent person, and hazards such as falls, falling objects, power lines and instability — written to OSHA 29 CFR 1926 Subpart L, the UK Work at Height Regulations 2005 with HSE scaffolding guidance, and NASC TG20 good practice for 2026. Local rules vary by country; it does not replace a scaffolder card such as CISRS or employer training. Score 70% or more on its 20 questions to earn a verifiable Scaffolding Proficiency certificate (SOA-SY). Every question is based on published standards and research — including Scaffolding (29 CFR 1926 Subpart L) (OSHA), TG20 guide to good practice for tube and fitting scaffolding (National Access and Scaffolding Confederation (NASC)), Scaffolding: construction safety topics (UK Health and Safety Executive) — and each answer is explained with its source.

Science of Apps offers a free Scaffolding Certification, updated for 2026 and 2027. It measures scaffold types, components and erection, platforms, guardrails and access, inspection, tagging and competent person and scaffold hazards and controls and gives instant results with a shareable certificate.

Score 70% or more and you get a Scaffolding Proficiency certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Scaffolding (29 CFR 1926 Subpart L) (OSHA); TG20 guide to good practice for tube and fitting scaffolding (National Access and Scaffolding Confederation (NASC)); Scaffolding: construction safety topics (UK Health and Safety Executive); Work at height: the Work at Height Regulations 2005 (UK Health and Safety Executive). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Scaffold Types, Components and Erection (Supported and suspended scaffolds, Components and Foundations and erection); Platforms, Guardrails and Access (Platform planking, Guardrail systems and Safe access); Inspection, Tagging and Competent Person (Inspection timing, Tags and handover and Defects and records); Scaffold Hazards and Controls (Falls and falling objects, Electrical hazards and Stability and weather). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Scaffolder or scaffold erector, Site supervisor or foreman, Scaffold inspector, Construction safety officer and Trade worker using scaffolds. It suits anyone who wants a quick, verifiable way to show Scaffolding knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

A competent person — someone with the training and experience to spot scaffold hazards and the authority to fix them — must inspect scaffolds. Under OSHA this happens before each work shift and after anything that could affect the structure; UK rules require inspection before first use, at least every seven days and after alterations or bad weather.

Under OSHA rules each scaffold and its components must support their own weight plus at least four times the maximum intended load. Suspension scaffold ropes must support at least six times the maximum intended load.
